IMPROVEMENT IN momma APPARATUS.

Specification forming part of Letters Patent N 0. 194,683, dated August28, 1877; application filed February 6, 1877. i

[0 all whom it may concern;

Be it known that I, EUGENEHU PH EY, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful or ImprovedTailors Pressing-Machine, which invention is fully set forth in thefollowing specification, reference being had to the accompanyingdrawings.

The object of my invention is to produce a tailors pressing-machinewhich shall bemore simple and substantial in construction and convenientand effective in operation than those now in general use.

My invention consists in the peculiar construction, combination, andarrangement of certain mechanical devices hereinafter fully described,which constitute a compact, convenient, self'contained, and durablepressingmachine, whereby the results are greatly facilitated and thelabors of the pressman re-' lieved. I y

In the accompanying drawings, Figure l is a top view of my machine withthe table or stand partly broken away. Fig.2 is a side elevation of themachine. Fig. 3 is a longitudinal section of the goose andacross-section of its connecting devices. Fig. 4 is alongitudinalsection of a goose with a boss, 1, cast thereon. Fig. 5 is a frontdetached elevation of a portion of the bracket, as seen from the rightof Fig. 2, and showing the face of cam E. Fig. 6 is a rear detachedView, as seen from the left of Fig. 2, showing the lever in verticalsection and the manner of its connection with the bracket.

A is a stand or table, which supports the machine and press-board. Thetop is of wood, and the legs may be of the same material; but preferablyof iron, of suitable construction.

B is a hanger or bracket, constructed of cast metal in one piece, and ofsuch form and special adaptation that all the operative parts areconnected and perform their functions relatively to each other, and theultimate results, either directly or indirectly through the agency ofsaid hanger, which, when properly mounted upon the stand, sustains thechief strain resulting from the counteraction of the active andresistant forces in the operations of said mechanism.

This hanger comprises the base-plate l, by which it is securely boltedto the table, the vertical body m, the horizontal extensions 1 above ando beneath the table, which serve, when properly bored.out, as guides andbearings for the vertical shaft 0, and its top is formed to receive theshaft or bolt u of the stop-cam H, as shown, while its lower end isbossed at q q to serve as the fulcrum of the treadle D when pressure isapplied to its free or pedal end.

Through this bracket, at n 0, and a suitable aperture out out in thebase-plate land tabletop, passes the vertical shaft 0, which issupported or guided thereby, and performs its functions therein, and tothe upper portion of which is journaled the goosesupporting arm E, whileat its lower end is pivoted the treadle I), at m. l

The goose-supporting arm, which thus swings upon shaft 0, is forceddownward. with said shaft through the agency of the shoulder thereonproduced by the enlarged portion which is journaled in bearing 11., andsaid arm is kept in contact with said shoulder through the agency of theset-collar y, and this arm is composed of two parts or members, E and F.Part E is of cast metal, and adapted to receive said shaft 0 and toafford suitable bearings for part F. Part F consists of a roundwrought-iron or steel bar, of suitable size and strength, and slides,for the purpose of lengthening and shortening the goose-arm,horizontally in the bearings t i, Fig. 2, formed in arm E, and may alsobe revolved in said bearings as the inequality of thickness of thearticle operated upon by the goose may require.

To the outer end of bar Fis attached the goose G, as shown in Figs. 1and 2, this goose being of the usual hollow construction and adapted tothe method of heating by slugs. Said attachment or connecting devicesconsist of a swivel, j, turning upon a screw, k, Figs. 3 and 4, which isthreaded and inserted in the upper side of .the goose, or in aconcentric boss, 7*, cast thereon, the ears of said swivel j (which isconstructed of wrought-iron) being adapted to receive between them theflattened end of bar F, and through them and said bar the bolt t passes,which completes the attachmentof the goose to the bar in such mannerthat it has a free movement in conformity to all the requirements of itsproper use.

The handle I is attached to the goose at one end only, in order to allowit a morenearly complete horizontal rotation in the swivel 7'. It moves,when thus connected, to and from arm 1*], with sliding bar F, swingswith arm E around shaft 0, rotates vertically with bar F, horizontallyin swivel j, and oscillates laterally on bolt t. Thus it accommodatesitself to all inequalities of thickness, and is conveniently brought tobear upon all parts of the,

way when not employed.

The treadle D is preferably of cast metal, and forked at one end, so asto embrace the lower end of hanger B, and slotted so as to receive thelower and flattened end of shaft 0, to which it is pivoted at It worksagainst the cast bosses or fulcrum q when pressure is applied to itspedal end, and is supported in position on said hanger, when itsopposite end is raised, by a pin, 10.

A spring, S, is attached to the under side of the table, and to saidtreadle, as shown, and serves to hold all the operative parts of themachine properly suspended and ready for use.

If preferred, the left-hand end of the treadle, as shown in Figs. 1 and2, may be extended a sufiicient distance, and an adjustablecounterweight attached thereto as a substitute device for spring S.

In practical operation, the goose G, with its supporting arm and bar-Eand F, moves conjointly with the shaft 0 in a vertical direction, whensaid shaft is operated by treadle D to produce pressure, and when it isagain reby'means of the spring S, or any other suitable device.

If deemed preferable, in construction the arm E-may be fixed rigidlyupon shaft 0, in which case the shaft may be made of a uniform size ordiameter throughout its entire length, and be fitted in and connectedwith the treadle D by any of the usual and wellknown methods whereby itmay be 'free to rotate on its axis therein, and in its bearings n 0,thus moving with the swinging arm E in its horizontal as well as itsvertical movement.

When convenience requires the goose to be held suspended at an elevationbut little above the level of the press-hoard, that it may movement ofthe shaft 0 at any desired point.

The cam H is attached to the hanger B by a screw or bolt, u, secured bynut a, threaded thereon and turned against a rubber washer or cushion,w, and is located over the end of the shaft 0 in such a manner that byso turning it the upward movement of said shaft is limited to any degreeof elevation within the scope of said cam.

In Fig. 2 the shaft is shown at its extreme elevation, it being incontact with the low section of said cam, while in Fig. 5 it is shown atits extreme depression, when at rest, said shaft being in contact withthe high section of said cam, which is kept from moving out of positionby the action of the machine, by force of said elastic spring, washer,or cushion to.

By this method ofadjustment Ido notchange arm upon its actuating-shaft(J, but adjustabl y limit the conjoint upward movement of both.

Force or pressure applied to the pedal end oftreadle D is transmitted,with unusual directness, through shaft 0, arm 1*], and bar F. to thegoose, and thereby acts upon the pressboard with a multiplied force inaccordance with the leverage gained in treadle D.

This method of longitudinally extending and contracting thegoose-supporting arm by means of a construction and arrangement wherebythe telescoping or sliding of one arm into or past the other iseffected, has an important ad vantage over the usual hinged arm, in thatthe force exerted through the former is invariably in a direct lineperpendicular to the axis of the actuating-shaft O, and thereby avoidsthe undue twisting and torsional strain which is unavoidable when theusual hinged arm is used; and, besides the direct and invariablevertical pressure thus produced, great advantage is derived from themultiplied power obtained thereby over those machines which rock thegoose-arm, and neutralize the'leverage gained in the treadle by theadverse leverage of the arm, through which the movement of the treadleis imparted to the goose.

With such last-named-machines the operator usually exerts'himsclf toproduce greater pressure by jumping while standing upon the end of thetreadle, and thereby renders his labor more irksome. In my machine thesimple resting weight of the operator upon\ the treadle is several timesmultiplied on the pressboard, and thereby the result is facilitated, andthe labor of the pressman relieved.

I do not claim, in a tailors pressing-machine, either in combination-orin theabstract, an arm arranged to swing upon or around a center in annnvarying plane, and to be extended or retracted in a direction radialto the circle, which it describes when moving in such unvarying plane,for I am aware that an arm and auxiliary devices susceptible of suchmovements, in conjunction with a goose upheld by such arm, have beenembodied in machines adapted to, and intended for, the purpose to whichmy invention relates; and that in the Letters Patent of theUnitedStates, issued to R. B. Sanson on the 2d day of September, A. D. 1873,is shown and embodied an arm having such twofold motion; but in thispart of my invention I limit my claim to an arm, and its immediatecoacting devices, so constructed and arranged that the bar or arm towhich the goose is immediately connected shall be susceptible of avertically-reciprocating movement, a swinging or vibrating motion in avarying horizontal plane, and also a horizontal sliding movement atright angles to the circumferential line described by'its movement in ahorizontal plane.

I claim as my invention- 1. In a tailors pressing-machine the hanger B,constructed with its sole-plate 1, vertical body m, shaft-bearings a 0,and fulcrum terminal for the treadle D, substantially as described andshown.

2. In a tailors pressing-machine the combination of the reciprocatingshaft (3, swinging arm E, combined and arranged to move vertically withthe shaft, and the sliding, bar F, all substantially as and for thepurposes specified.

3.111 a tailors pressing-machine the hanger B, formed substantially asdescribed, shaft 0, treadle D, and a goose-supporting arm, com"- binedand arranged to operate substantially as and for the purpose specified.

4.. In a tailors pressing-machine the combination of the treadle D,vertical shaft 0, arm E, and sliding bar F, constructed and arranged tooperate substantially as specified.

5. In a tailors pressingmachine the combination of theautomatically-raised vertical shaft 0 and adjustable cam H, to check theascent of the shaft, but admitting a free descent thereof, allsubstantially as described and shown.
